Quote: Ok i have read this entire article. questions 1. bore-stroke of the 5.7 2. bore-stroke of the 6.1 3. bore-stroke of the 6.4 if going to bore-stroke the engine, would the 5.7 be the least expensive(it will be in the car)? can the early heads on the 5.7 be ported to the size of the eagles? I'm confused on the cams working with the older vs new head? machined differently? My project was to find an older Challenger then install the 6.1 engine,($5200.00) now it looks like the 5.7 would could be made up just as well, later upgrade to the hellcat supercharger. This is all new to me so steer me right please.
1 3.92 x3.58 2 4.055x 3.58 3 4.090x 3.72 4 bore and stroke will be cheapest depending on which block is cheapest. yes don't know about finding a new 6,1. good luck and jump on it if you find one. Matt

can get a used one with 59,000 miles for $5200 out of a Charger with accessory's and boxes or one for $4,000 with 100,000 miles. maybe sell the 5.7
